What NEC says about design constraints for grounding systems
Several key design constraints for grounding systems from the NEC are as follows. These are paraphrased from the code text: Ø Electrical systems that are grounded must be grounded in such a manner as to limit the voltage imposed by lightning, line… Read more

How to get rid off the harmonics in electrical system?
The subject of harmonics is also a contributory factor in electrical noise I already wrote few days ago (Cable spacing as a means of noise mitigation). It also causes several other problems in power circuit components such as motors, transformers and capacitor… Read more

The Advantages Of Maintaining A High Power Factor
A high power factor eliminates penalty dollars imposed when operating with a low power factor. For many years, most utilities demanded a minimum of 85% power factor as an average for each monthly billing. Now many of these same utilities… Read more
